POWER-CONVERTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 588,481, dated August17, 1897.

' l 7 Application filed May 7, 1897. Serial No. 635,465. (No model.)

Louisville, in the county of Jefferson and State of Kentucky, haveinvented a new and Improved Power-Converting Mechanism, of which thefollowing is a full, clear, and exact description.

My invention relates to an improved mechanism for use in convertingreciprocating into rotary motion.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar characters of reference indicate corresponding parts inboth the views.

Figure 1 is a side elevation of my device; and Fig. 2 is a plan View,certain portions being broken away to show other parts.

My device consists,' essentially, of bars pivoted together in one ormore pairs, similarly to the two bars of a toggle-joint. The outer endsof these bars are restrained within guides, so that they have areciprocating movement therethrough, and may be also provided with shortarms, extending at right angles thereto, at their outer ends. These armsare connected by rods with double cranks placed upon a shaft. Themovement of the center pivot of the bars forming the toggle-joint causesa reciprocating movement of the connecting-rod and therefore a rotarymovement of the shaft.

In the drawings the frame supporting my device is represented by A. Thisframe car ries a shaft B, mounted thereon and provided,

as shown in the drawings, with two sets of double-crank arms 0 C. It isalso provided with a fiy-wheel D, which contributes to steadiness ofrotation.

At each end of the frame A are bars G, extending across the same andforming guidepins for the bars F. These bars F are pivoted to each otherat'their inner ends, as shown at H. Their outer ends are provided withslots f, through which the guide pins or bars G pass. From the outerends of the bars F project arms F substantially at right angles thereto,and to the ends of these arms are connected the rods E, which at theirother ends are connected to the pins of the cranks C. One set 'of bars Fwill be elevated while the other is depressed, the connection of eachset being made opposite to that of the other set.

By means of this device a small power applied at H will exert a greatrotating effect at the shaft 13.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A power-converting mechanism, comprising two leverspivoted to each other at one end, forming toggle-levers, a frame havingguides for the outer ends of said levers, side extending arms attachedto said outer ends, a shaft mounted in said frame and having double andopposite cranks, and links or connecting-rods connecting said crankswith the outer ends of the side extending arms, substantially asdescribed.

.2. A power mechanism, comprising a shaft having two pairs of doublecranks all arranged in the same plane, two sets of bars pivoted to eachother to form toggle-levers, guides for the outer ends of the said bars,arms extending at right angles to said bars at their outer ends, andaway from the apex formed by said bars, and connecting-rods connectingthe outer ends of the said arms with-the cranks, substantially asdescribed.

BENEDICT J. ROSS.
